Answer:
The path around the normal purchasing channel is known as Maverick Spending.
Step-by-step explanation:
The Maverick spending refers to expenses made from purchases outside the original contract, breaking the rules of previously established processes. In this example, one professor decided to disobey the original agreement and find another supplier, even though that would increase the expense greatly.
This is an actual problem for many different companies that are trying to eliminate by implementing different measures such as spend analysis, a list of verified suppliers or purchasing control.
